wjw. BURSON, OF YATES cI'rY ,-I LL-INo I s IMPROVEMENT IN GRAIN-BINDERS.

To all-whom it may concern:

Be it known that 'I, W. W. BURSON, .o'f Yates City, in the county ofKnox and State of Illinois, have invented a new and useful Grain-Binder;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawing,formingpart of this specification, in the several figures of whichsimilar characters of reference denote the same part.

Figure 1 is a side elevation, the upright B being removed. Fig. 2 is atop view, the'arm A and its attachments being removed. Fig.3 is a frontperspective view of the-devices for tying, cutting, and fastening thetwine, the grain-board T being removed. Fig. 4 is a top view of thehooks a and z and receptacle 0. Fig. 5 is a face view of cam-wheel at.

My invention hasreference to'binding grain .(with twine) upon theplatform of any reapingmachine before it (the grain) is thrown upon theground; and consists of certain combinations of devices hereinafter tobe set forth.

In the drawing, R R support the jointed arm A by rod D. The grain-boardT protects the tying apparatus, and serves as-a support for hook at. Theplatform K receives the grain preparatory to binding. L Lare' guides tothe arm A across the platform K. The 'opening M in the platform K allowsthe blades and other rubbish to fall through without interfering withthe tying apparatus. The cord 0 is attached to the partA ofjointed armA,around the rear portion of said arm to the fastening W.

The cords B are attached. to A at V, and pass through E, over pulley V,around the rear portion of A to their fastening W. The crank .0 rotatesthe shaft r, upon which are fastened the cam-wheelsfand d, thecutting-point i, and hook P. The hook it rests upon wheel d by forkedarmw, relieved by friction-roller w, theupper part moving in slot y,relieved by roller H. The bent lever S moves upon bearing t, the rearend working in track g of cam-wheel d.

The book ais made somewhat wedge-shaped, and fits its receptacle 0, Fig.4, and is held firmly in said receptacle by wheel f pressing uponfriction-roller b until the cam upon said wheel drives it forward toslotted book 2, and immediately brings it back to its place of rest.

The cutting-point i is fastened upon shaft 1*, and severs the twineafter the knot is tied by 'the operator then takes hold of arm A,forward of D, and'by raisin git the rear portion presses upon cord 0 andextends the arm, as shown in Fig. 1, (dotted lines.) The tying apparatusthen being in position, as shown in Fig. 2, the machine is in readinessfor the grain upon platform K when placed thereon. Then arm A, is moveddownward; the rear part presses upon cords B, which draw arm A downwardand across the. platform K under the grain.'

The nozzle-pieces H H E, pa-ssing'severally below,between z and abovethe hooks P and Z, direct and drive the portion of twine which isstretched from the hole and over notches in nozzle-pieces H H H uponsaid hooks, which now hold the band material for completing the boundsheaf. The arm is then backed an inch or two for the purpose ofpreventing interference with the knot-tyin g apparatus. When theoperator with his left hand turns the crank O to the right, the rear endof lever S in groove 9 is brought inward toward the center, therebymoving the front end with twine forward and outward,.and also therebyassist-ingin forming space for the descent of hook it when the hook Phas formed a loop. The book a, obeying the shape of cam-wheel 02, nowdescends into said 1009, and passing below the twine stretched from hookz to lever S, it draws it upward through the loop. Simultaneously withthe upward movement of hookuthelever S returns 'to its position of restunder shield h, and the hook a,-which is now driven forward by the camupon wheel f, suddenly releases the twine. it was holding, its roundedend passes beyond the twine, and on its return it carries and firmlywedges it into receptacle 0, thereby forming and securing the band forthe next sheaf. Then the cutting-point i sever-s the twine, and thesheaf is ready for removal when the arm is again raised.

v In constructing the machine, the shaft R is placed horizontally. Thehook P-is placed eccentrically upon the shaft R,.thereby permitting hookat to enter the said loop'at the left side of said shaft, whicharrangement, assisted by the oblique position of hook u, removes theloop from book p by its rotation.

The bent leverS is'obtusely pointed, which form permits shield h toremove the twine from said point when the knot is being tied. The book Pis placed superior to, or above and perpendicularly to, hook 2, whichform and arrangement is necessary in order to insure their certainreception of twine from nozzlepieces on arm A. The hook z is parted andhas a groove, in which book a passes, thereby causing it to act withcertaintyin securing or taking the twin-e from said hook z, andpermitting a continuous renewal of the aforesaid operations until the,ball or spool of twine is exhausted.

Whatl claim, and desire to secure by Letters Patent, is-

1. Extendingand contracting the fore arm A by the action of the rearportion of A upon the cords B and O, substantially as set forth.

2. The combination of the books 2 l u and the bent lever S, operatingsubstantially as described.

3. The arrangement of books P and u;

whereby the latter is passed through the loop,
